摘要： An operation method includes measuring figure of merit (FoM) values for a first group of presets having different preset types, based on equalized signals output from a transmission equalizer included in an external device adjusted based on the first group, identifying a preset type of a first preset corresponding to first FoM value which is a greatest value from among the FoM values for the first group, measuring FoM values for a second group of presets having the identified preset type, based on equalized signals output from the transmission equalizer adjusted based on the second group, determining a second preset corresponding to second FoM value which is a greatest value from among the first FoM value and the FoM values for the second group, and transmitting an equalizing setup request that controls the transmission equalizer to the external device, based on the determined second preset.

摘要： The invention relates to precoding (or rather pre-equalisation) for a faster-than-Nyquist OFDM or OFDM/OQAM-type transmitter. Compression of faster-than-Nyquist OFDM pulses over time introduces an inter-symbol interference (ISI) and a sub-carrier interference (ICI). Assuming a Gaussian-type channel (AWGN), the ISI and ICI can be estimated at the transmitter and, in this way, some of the symbols (at most half) can be precoded (according to the value of the adjacent symbols), such as to cancel the ISI and ICI introduced during transmission and reception.

摘要： A method of controlling an input signal supplied from an encoder to a modulator, wherein the input signal causes modulation of a current flowing through a light source in order to embed data in light emitted by the light source. The method comprises: for each of a plurality of possible logical transitions allowed by the encoding scheme from an adjacently preceding symbol to a present symbol, determining a respective observed value for the current level of the present symbol; for each of the plurality of logical transitions, determining an associated error between the respective observed value and a corresponding one of a set of nominal values for the current levels; and based on the respective error for each of the plurality of logical transitions, applying a respective compensation to the corresponding input in order to bring the resulting current level closer to the corresponding nominal value.
